Label Searches, Using Combinations Of Labels

Blog owners have been asking for the ability to search for posts using label combinations, for a while.

That option was given us, some time ago - with no fanfare. What we now have is called a "Boolean" label search.

It's not difficult to use a Boolean label search - when you understand what it does.

Here are 3 examples, from this blog.

Here are 3 labels, and their label search URLs, chosen "at random" from this blog.

• Comments http://blogging.nitecruzr.net/search/label/Comments
• Cookies http://blogging.nitecruzr.net/search/label/Cookies
• Filters http://blogging.nitecruzr.net/search/label/Filters

Combining the 3 labels, we get

• Comments+Cookies+Filters http://blogging.nitecruzr.net/search/label/Comments+Cookies+Filters

It's actually easier to do it, than to read about it - but if you wish, you can click on each of the above 8 links (all using " target="_blank"", to open separately, for your convenience), and compare the posts indexed.

Be aware of the limits, and use this option selectively.

There are 3 unfortunate limits, here.

1. You can't use the "+" symbol, in a label. I have a label for "Google+", in this blog, which does not work.
2. You can only do "+" (Boolean "AND" / "Intersection") combinations, no "-" (Boolean "OR" / "Union") combinations.
3. You have to build the lists, and the URLs, yourself. There is no handy Topics list, that supports selecting 2, 3, or more labels.

But, if you can deal with the limitations, this is a pretty powerful option.
